How is Diethylene Glycol (DEG) Produced?
The production of diethylene glycol primarily occurs as a by-product in the production of monoethylene glycol (MEG). This process involves several key steps:
Oxidation of Ethylene: The process begins with the oxidation of ethylene. This is done at a high temperature, typically using a silver oxide catalyst. The oxidation of ethylene results in the formation of ethylene oxide, a crucial intermediate in the production of various glycols.
Hydration of Ethylene Oxide: The ethylene oxide then undergoes a hydration process. In this step, the ethylene oxide reacts with water, leading to the formation of different types of glycols. This reaction produces monoethylene glycol (MEG), diethylene glycol (DEG), and triethylene glycol (TEG), among others.
Product Separation: Once the hydration reaction takes place, the different glycols are separated out based on their properties. While the primary aim of this process is often the production of MEG due to its extensive industrial applications, DEG and TEG are valuable by-products.
The chemical industry tends to focus on maximizing the production of MEG because of its high demand in various applications such as in the manufacturing of polyester fibers, polyethylene terephthalate (PET) resins, and antifreeze formulations. However, diethylene glycol also finds its use in a variety of applications, including as a solvent, humectant, a plasticizer, and in the manufacture of unsaturated polyester resins, polyurethanes, and plasticizers. As such, even though it’s a by-product, DEG is a valuable component in the chemical industry.
